RE: The old challenge: HP-35 on Arduino
(09-27-2018 11:52 AM)teenix Wrote: Although the AVR has less memory, I can't see why this wouldn't be possible as I was able to squeeze 27 HP models onto a single PIC chip. There is no problem at all, just a small challenge for youngsters still learning... From another point of view, additional savings may be in different approach to decode and execute instructions. I have not looked more explicitly in the Pietro's code, however I had a bit different approach when I made my own HP-35 emulator, which can be better or worst regarding used ROM space on this platform. The approach I made allowed much easier implementation of MOSTEK emulation for desktop application, including assembling and disassembling... I believe Pietro made optimal algorithm respecting limited space and speed for this platform, since it was not an amateur at all in computer science in that time. |
